dm cache: set needs_check flag after aborting metadata
Otherwise the commit that will be aborted will be associated with the
metadata objects that will be torn down. Must write needs_check flag
to metadata with a reset block manager.
Found through code-inspection (and compared against dm-thin.c).
Cc: stable@vger.kernel.org
